MACHINE FOR PLACING WASHERS IN HEEL-HOLDS.

Specification of Letters Patent.

Application led August 25, 1919. Serial No. 319,550.

To all whom it may concern Be it known that we, BENJAMIN W. Mm- '.rrN and HOMER SAMS, citizens ofthe United States, residing at Zanesville and Akron, 1n j the counties of Muskingum and Summlt, and State of Ohio, have invented new und useful Improvements in Machines for Placin Washers in Heel-Molds, of which the focwing is a specification. 1g This invention relates 'to means for applying the washers to the pms in the molds tor forming rubber heels and the principal object of the invention is to provlde means whereby said washers may be placed on a u large number of sets of pins at one operation and'with but a few movements of the .parte Another ob'ect of the invention 1s to provide means or automatically feeding the M, washers to the point of delivery and in a position to be passed over the pins when the puny. in means are lowered. fil Anoter object of the invention is to provde means for releasing the washers, -utter placed on the pins from the delivery *.jmeans and at the same time releasin the locking means which hold the de lverjr means in the loweredt position. n

The Ainvention also consists in certain y; ,other features of construction and in the ,combination and arran ement of the several yto be hereinaer fully described, in the accompanying drawings .1 specifically pointed out in the appended describing our invention in detail, reference will be had to the accompanying drawings wherein' like characters denote Llike or corresponding arts throughout the wfaeveral views, and. in w ich I i? A e l is a side view of the inventlon i ,showing ghe lower part of the mold in sec- A i f 2 lis a sectional view;

i iis a f- -vlew of the curved these views 1 indicates the mold plate which theshouldered pins 2 are arranged groups. plate is provided with the :L 0119 .IS lcaftd 011 each y itwelvm'g the legs of my @This devicefoonsists of a.

= corner is provided with the depending purl.' 5 and euch part has adjustubly secured thereto the which has a rounded end for enga ing the recess 3. When the legs are place in the recesses the device will be properly positioned in respect to the mold plate. The upper edge of the frame has an upwardly depending flange 7 and this flange forms u rectangular recess in which is located n plate 8. This plate is normallyv held in u raised position above the bottom of said recess by means of the spring plungcl's 9 carried liv the franne. The plate 8 is provided with un upwardlyv extending flange l0 which'is located an appreciable distance from euch of its side edges and said flanges forni a chamber for receiving the washers. Hthin this chamber the plnte is provided with thc slots 1l which are arranged in groups, shown in the plan view und the slots of euch group are arranged according to the arrangement of nail holes in the heel. The slots lead to the curved tubes l2 which ure suitably connected to the bottom of the plate. Euch of these tubes is curved in Such u manner as to hold the lowermost washer inn horizontal position directly over u pin. Each tube earries a spring plate 13 which has its lower end bent over the outlet end of the tube to )Fevent the washer from leaving said end. he bottom edge of said outlet end of each tube is recessed ns at ,i4 to receive tho pin and thus permit the washer to pass over said pin. The tubes may be split as shown though this is not necessary. ln order to cause the washers to pass into the slots I provide rounded and peuked projections 1.5 olnithe upper fuce of the plate 8 around said s ots.

As before stated, the plungers will hold the plate with the tubes holding the lowermost Washers in a position directly over the pins so that when the plate is lowered said washers will pass on to seid pins and rest upon the shoulders thereon. In order to lower said plate I provide a hand level' 16 pivoted on a shaft 17 carried by ears 18 on Vtwo of the side members of the frame, intermediate their ends and this lever is connected by the rods 19 to the levers 20 can ried by the shafts 20 which are pivoted to the ears 2l located at the corners of the frame. At each end of each shaft is located an arm 22 which carries a roller 22, which engages with the upper fece of the plate 8 nt each corner thereof. The arms all extend leg (i in the same directon so that when the lever is actuated said arms will be moved into a substantially vertical tion so that the rollers thereon engagm the plate 8 will force the same downwar ly thus depressing the plate sothat the washers are laced over the pins. Later l movement of t e plate is revented by its front edge engaging the an e on 'the frame. I provide means for hol ing the plate in its lowered position and these meansconsist of a dog 30 carried b the lever 16 and adapted to engage a note quadrant 31. This og is hel 1n engagement with the notch by means of a sprm plun er 32 having one end connected wit the og andY its other end engaging a guide 33 on the lever. After the plate is lowered it is moved rearwardly to release the washers from the tubes by means of a lever 23 secured on the shaft 17 and having its lower end connected by link 24 to luv 25 carried by the front of the plate. hus when the lever 23 is actuated the late 8 will slide rearwardl so that the was ers on the pins will be re eased from the ends of the tubes, the springs 13 being forced upwardl by said washers. As the lever 23 1s move it will rock the shaft 17 thus causing the cam 34 on said sha-ft to engage a plunger 35 which has its u per end connected with the dog 30. Thus t e dog will be raised out of engagement with the notch to permit the arts to assume their normal raised position. Il`hen the lever 23may be returned to place the plate in .pro er positionfor being lowered a ain. e device may then be lifted oil' t e moldplate and placed on another one and the same operation carried out.

In this way a great number of groups of washers may be placed on the pins at the same time.

It is thought from the foregoin d'escription thatthe advanta es and nove fea-tures of our invention wil be readily apparent.

We desire it to be'understood that we may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall withinthe scope ofthe appended claims.

What we claim .is 1,-

1 A derlice'of the glass described cpmprising a ame awas er su porting pate su orted thereby,eurved tubes carried by sai plate and the washers there- --ing a frame,

from, spring carriers for, holding the washers in said tubes, means for lowering the plate to place the 'washers on the pin and means for moving the plate laterally to release the washers from .the tubes. y

2. A device of the class described comprisa washer supporting plate carried thereby and having slots therein `for the passage of the washers, pro'ections for directing the washers into the s ots, curved tubes connected with the bottom of the plate and communicating with the slots, spring latches holding the washers in the ,tubes, manually operated means for lowering the plate to place the lowermost washers in the tubes over the pins in the mold plate and means for rmfrving the plate laterally to release said Washers from the tubes.

3. A dece of the class described comprising u frame, a washer su porting plate carried thereby and having s ots therein, curved tubes connected to the bottom of theplate and communicating with said slots, spring latches for holding the washers in the tubes, means for lowering the plate for bringing the lowermost washers 4in the tubes over the pins in the mold plate and means for moving the plate laterally to release the washers from the tubes and at the same time release the lowering means.

4. A device of the class described comprising a frame, a washer supporting late carried thereby, spring means for ho ding said plate in its raised position, washer delivery means carried by said plate, means for lowering the washer supporting plate to .lace the washers on the ins and means or moving the washer llate laterally to release the washers from `e delivery means and at the sume time release the lowering means.

5. In combination with a mold plate hav-- ing recesses therein, a washer delivering device comprising a frame having depending legs forengaging said recesses, a movable plate in said frame, delivery tubes carried y said plate, means for delivering the Washers to said tubes, means for lowering the washer plate to place the washers on the pins and means for moving the plate laterally to release said Washers from the tubes.
